The relationship between soil moisture and crop growth

The impact of soil moisture on crop growth

Promote root development

Appropriate soil moisture can promote the development of plant roots, thereby promoting the overall growth of plants. When the soil moisture is between 40% and 70%, most plants can achieve the best growth rate.

Affecting water absorption

Soil moisture directly affects the absorption of water by crops. If the soil is too dry, the plants will lack water and their growth and development will be restricted; if the soil is too wet, the roots of the plants will easily rot, which will also affect the normal growth of the plants.

Regulating soil aeration

Soil moisture and soil air occupy the pores of the soil. The more water, the less air, and the less water, the more air. Therefore, by controlling soil moisture, soil aeration can be changed, thereby affecting the respiration of crop roots and aerobic microorganisms. For example, shallow irrigation, wetting, and intermittent irrigation methods are used for rice, and methods such as intertillage and loosening of dry fields are all measures to enhance soil aeration.

Measurement and regulation of soil moisture

Measurement method

Soil moisture measurement requires a soil moisture meter, which can help farmers adjust the irrigation amount and irrigation cycle by monitoring the plant growth environment, so that the root soil moisture remains at a reasonable level.

Regulation method

In order to maintain the root soil moisture within a suitable range, the correct irrigation method is required. Different irrigation methods and irrigation amounts are selected according to the amount of water required by different plants and the characteristics of the growth environment. In addition, maintaining the air permeability of the soil layer and avoiding long-term water accumulation and root rot are also important regulatory measures.

Application of soil moisture detector

Soil moisture detector is an important agricultural tool that can monitor the changes in soil moisture in real time and transmit data to farmers' mobile phones or computers, so that farmers can keep abreast of the soil moisture situation at any time. In this way, farmers can adjust the irrigation amount in time according to the changes in soil moisture to ensure that crops get enough water, thereby ensuring a good crop growth environment.

Conclusion

Soil moisture has a vital impact on crop growth. Through reasonable irrigation and the use of soil moisture detectors, farmers can effectively control soil moisture and ensure that crops get a suitable water supply, thereby promoting healthy growth of crops and increasing yields.
